Delaware Route 15

Delaware Route 15 (DE 15) is a state highway in the U.S. state of Delaware. The route runs from DE 14 west of Milford in Kent County to U.S. Route 301 (US 301)/DE 71/DE 896 in Summit Bridge, New Castle County, just south of Summit Bridge over the Chesapeake and Delaware Canal. DE 15 winds a path through many rural sections of Delaware, turning along many different roads. Most of the route, with the exception of the southern part of the route from Canterbury to Milford, runs to the west of US 13. Delaware Route 15 runs through the western outskirts of several cities and towns, including Wyoming, Dover, Clayton, and Middletown. The route intersects DE 12 near Felton, US 13 in Canterbury, DE 10 near Camden, DE 8 in Dover, DE 42 in Seven Hickories, DE 300 and DE 6 in the Clayton area, US 301/DE 299 in Middletown, and DE 286 near Summit Bridge.

What is now DE 15 was paved in several stages from the 1930s to the 1960s. By the 1980s, the route was designated between DE 14 in Milford and US 13 in Canterbury. By 1990, it was extended north to US 301/DE 299 near Middletown and then to US 301/DE 71/DE 896 near the Summit Bridge by 1994.
